Switching cabinet

Abstract

A switching cabinet having a rack with horizontal and vertical frame profiles. The horizontal frame profiles form a lower and upper frame and the vertical frame profiles are secured in the comer areas of the upper and lower frames. The vertical frame profiles are symmetrical to cross-sectional diagonals running across virtual, vertical outer edges of the rack. Greater flexibility in installing built-in fixtures inside the switch cabinet is achieved by providing the vertical frame profiles which are turned towards the inside of the switching cabinet with an open inner cavity having two inner walls extending in the longitudinal direction of the profiles so that vertical assembly rails can be mounted in the inner cavity, one profiled side standing perpendicular to the outside of the rack is joined to the inner walls. The inner walls, the assembly racks and the profiled sides can have rows of fastening cavities inserted according to a division grid.
